File contents

feishu-audio

Send TTS audio to Feishu as a playable audio message (msg_type=audio), not a file attachment.

Why This Skill Exists

OpenClaw's message tool sends audio as a generic file. Feishu requires a two-step API flow to display it as a playable voice message:

Upload with file_type=opus
Send with msg_type=audio

Quick Usage

bash /root/.openclaw/skills/feishu-audio/scripts/send_audio.sh \
  "要说的内容" \
  "<chat_id or user open_id>" \
  [voice]          # optional, default: zh-CN-XiaoyiNeural

receive_id_type is always chat_id. For group chats use oc_xxx; for DMs use ou_xxx (open_id).

Common Voices

Language	Voice
Chinese (F)	`zh-CN-XiaoyiNeural` (default)
Chinese (M)	`zh-CN-YunxiNeural`
English (F)	`en-US-AriaNeural`
English (M)	`en-US-GuyNeural`

Credentials

Auto-read from /root/.openclaw/openclaw.json → channels.feishu.accounts.main. No manual setup needed in standard OpenClaw deployments.

Two-Step API Flow (for custom integrations)

# Step 1: Upload (file_type=opus is required regardless of actual format)
curl -X POST "https://open.feishu.cn/open-apis/im/v1/files" \
  -H "Authorization: Bearer $TOKEN" \
  -F "file_type=opus" -F "file_name=voice.opus" -F "file=@audio.mp3"
# → returns file_key

# Step 2: Send (msg_type=audio, NOT file)
curl -X POST "https://open.feishu.cn/open-apis/im/v1/messages?receive_id_type=chat_id" \
  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '{"receive_id":"oc_xxx","msg_type":"audio","content":"{\"file_key\":\"...\"}"}'

Key pitfalls:

file_type must be opus (not mp3) or upload returns 234001
msg_type must be audio (not file) or it shows as attachment
